It's Snake with a twist; it gets dark and you can't see your tail but you still die if you hit it.
I made it so that there are 2 kill conditions: if the head hits a wall (already there), and if a clone that has been alive for more than 0.4 seconds touches the head (if you look at costumes, you'll notice the head is 5% lighter than the body), a color detection system will be tripped. I also made it so you can't go back into yourself without turning, added a turn delay so that you won't accidentally turn to fast, and added a world high score counter (only works for "scratchers').
